The defacto leader of the Movement for Democratic Change (MDC) Renewal Team and former Finance Minister Tendai Biti, is warning that Zimbabwe might descend into chaos as the Zanu-PF led government grapples with internal factional fights and an imploding economy.

Biti told VOA Studio 7 that President Robert Mugabe’s ruling Zanu-PF party has no clue on how to deal with these two issues.

Biti said Zimbabwe is in a very fragile state. "We have never had this multifaceted crisis coinciding at one point.”

Biti added, "The Zimbawe government is very weak, so Zimbabweans need to be concerned about what is happening in Zanu-PF, because when you have the combination of a weak government, when you have the combination of a weak ruling party, when you have the combination of a weak economy, that is invitation for political instability including unlawful, and unconstitutional things such as a military coup."

The former finance minister urged opposition political parties in Zimbabwe to unite, noting that his party is in the process of re-organising.

He said they will hold their own congress next year after splitting from rival MDC-T leader Morgan Tsvangirai.

Tsvangirai and Biti had been long-standing allies in their campaign to remove Mr. Mugabe from power, but fell out after the elections held in July last year.

Tsvangirai said Biti and the other "rebels" had been recalled from parliament.

In turn, Biti's faction said the MDC's National Council had voted to suspend Tsvangirai because the party had been "transformed into a fiefdom of the leader".
